SEE
The smallest, most capable 500 W
power supply of its kind.
Overload-, overvoltage-, thermal-pro-
tection and integral covers are standard.
All NMX power supplies can be ordered
self-cooled with internal ball-bearing fans.
The NMX 350 and NMX 500 are available
without fans for use with system air
cooling.
All outputs are OEM-adjustable
and 3 V main outputs are available.
Integral RFI filters allow every NMX power
supply to meet conducted emissions of
EN55022 class B and FCC Class A.
Compliance is also provided for interna-
tional safety requirements including IEC
950 and the requirements of IEC 555-2
for harmonic line distortion.

SPECIFICATIONS: ALL MODELS
INPUT
AC Input:
90-264 Vac continuous range, 47 to 63 Hz. Internally fused for 10 A.
Power Factor:
0.99 typical at full load. Meets EN61000-3-2.
Inrush:
Cold start AC current is less than 30 A at 115 Vac and 60 A at 230 Vac. Limited by
thermistor.
Brownout Protection:
Holds regulation to 85 Vac.
Holdup Time:
20 ms minimum after removal of power at full load.
Efficiency:
75% typical.
AC Power Fail:
Provides TTL “0” 5 ms before output voltage goes out of regulation band
upon loss of ac power.
OUTPUT
Adjustability:
Outputs #1 and 2 user adjustable ±5% minimum. Output #3 tracks #2; initial
accuracy ±4%. Output #4 user adjustable ±5% minimum, or +5% only if voltage is 5.2 V
Line & Load Reg:
Outputs #1, 2, and 4 hold ±1% over AC input range and 0 to 100% load
change. Output #3 requires 20% minimum load on outputs #2 and 3 to hold ±4%.
Ripple & Noise:
Less than 1% p-p or 100 mV, whichever is greater.
Remote Sense
(Outputs #1 and 2): Compensates for 250 mV total line drop. Open sense lead
protection. (See Redundancy, below.)
Temperature Coefficient
(Outputs #1, 2, and 4): 0.02% per degree C.
Stability:
0.1% over 8 hours after 30 minutes warm-up.
Transient Response
(Outputs #1, 2, and 4): Output voltage returns to within 1% in less than
500 µs for a 50% load change. Peak transient does not exceed 5%.
Overload Protection:
All outputs are protected against overload and short circuit. Automatic
recovery upon removal of fault.
Overvoltage Protection
(Outputs #1 and 2): Protects load against power supply induced
overvoltage. Trip point is factory set so that output voltage cannot exceed 136% of nominal.
Peak Output Current:
Dual current ratings define continuous and peak currents. The peak
current shown can be delivered for a maximum period of 30 seconds.
Remote Inhibit:
Contact closure to the negative sense line or a TTL level “0” turns off DC
outputs.
DC Power Good:
Provides a TTL “1” open collector when output #1 is above 4.6 V nominal.
Redundancy:
External OR-ing diodes and forced current sharing on output #1 provide “N+1”
capability. Remote sense (+S) compensates for additional 0.6 V diode voltage drop. When
the current sharing terminal is connected between units, current sharing remains within
10% of the unit’s full output current rating. For hot swap applications see TMX 350.
Reverse Voltage:
Protected against reverse voltage up to supply current rating.
ENVIRONMENTAL
Thermal Protection:
Shuts down power supply if overheated. Automatic recovery.
Temperature Range:
0° to 50°C at full ratings.
Safety Agencies:
Most models are approved to UL1950; CSA 22.2 #234; IEC 950 and TÜV
EN60950, Class 1 SELV., CE 72/23/EEC/93/68EEC (low voltage directive).
Conducted RFI:
Meets FCC Part 15, Subpart J, Class A; EN55022 Class B; CISPR 22 Class B.
Output Isolation:
Isolated from ground 50 Vdc.
Cooling:
30 CFM required to achieve full ratings.
Dimensions:
OPTIONS:

Millimeters
Option “F”, Fan/Cover Assembly:
Cover with integral ball-bearing fan provides proper cooling
to achieve full ratings at 50°C ambient temperature. 2.05” dimension increases to 3.28”.
Option “V”, Fan/Cover Assembly:
Low profile, end venting cover with integral ball-bearing fan.
2.05” dimension increases to 2.50”, and 9.65” dimension increases to 11”.
